Cutting to the chase, in the little things do matter column:
""The introduction of notches, probably caused during the bush removal process, introduced stress [risers] into the small end, increased the likelihood of fatigue crack initiation and therefore fatigue failure."
Referring to the Con rod rebushing screw up by a hand angle grinder that was likely the cited cause of the calamity.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

I think all the large ship diesel engines have removeable inspection plates into the crankcase large enough for a man to walk into and have to look up to see the wrist pins The comment about a man standing beside one is a good example of the large sizes

Yikes.
Hopefully that rebuilder doesn't offer Mopar crate engines. They probably torqued by feel, because experience you know.

My father was a engineer and later got his Chief engineer license for medium ship diesel engines, those engines are HUGE Very low speed RPM wise also, maybe 1200 RPM max, maybe less or a little bit higher In the marine world, that is considered a high speed diesel. The big ocean going units are slow speed, in the 80-120 RPM range. Kevin

The utility I worked at had a number of '40's era diesel generating plants. Rating was about 2.4 MW per unit IIRC. The plant manager started one up for us on a visit and it was chugging along at about 800 rpm and I asked him when he would take it off idle. He looked at me funny and said that it was already at governed speed.

Torque at peak HP is just over 199,000 ft/lbs. Not sure what peak torque is but I suspect it's approaching the outer limits of a 727 Torqueflite . Kevin

Given the size of that engine. If they can't take the block out in pieces I can't see a way to fix it that would be cheaper than a new boat. Even if you can remove the block in pieces I think your gonna have a big, big, problems getting pieces that size out of the hull. I don't know but it seems like they totaled a ship.

Not at all, cut out the deck(s) above, hoist it out, put new one in, weld decks back in. Not uncommon in ship repair.

They won't total a ship that size. They'll cut a hole in the side and out it goes. Saw them do that in a documentary on TV one time. Crazy amount of work/time/money but that's what they do. Here they are doing a cruise ship in the same manner: https://www.youtube.com/watch?v=pw6-82YVIbE

Of course anything is doable, but there are of course many other factors involved in deciding what is the best solution/repair, like age of the hull, cost of a replacement engine, market that the ship serves, overall environmental footprint of the ship in regards to current or future expected regulations, its cost to operate relative to the competition, and the depth of the pockets of the owner or who ever foots the bill, and lastly, how close is the ship to Bangladesh https://en.wikipedia.org/wiki/Ship_breaking
